r/>Thus, when a rate of change of one ampere per second in the primary coil will produce one volt in the secondary coil, the two coils have one henry of mutual inductance.
It should be taken into consideration that induction by a varying current results from the change in current not in the current value. The faster the current changes, the higher the induced voltage.
Find the correct variant. Remember it:
1. any conductor has
a) some definite value of resistance
b) some definite value of inductance
2. any conductor can provide
a) electric power
b) induced voltage
3. elements with a definite value of inductance
Al are called inductors
b) are called coils
c) are called sources
4. the inductance of a coil depends upon
a) its size
b) its core
c) its material
d) its number of turns
5. an iron core
a) increases the value of inductance
b) decreases the value of inductance
6. the value of mutual inductance is measured
a) in watts
b) in henries
7. induction by a varying current
a) results from the change in current
b) results from the change in the current value
8. the faster the current changes
a) the lower the induced voltage
b) the higher the induced voltage
Answer the following questions:
1. What value of inductance have conductors? 2. What is the function of inductors?3. How are elements with a definite value of inductance called? 4. What does the inductance of a coil depend upon? 5. How does the inductance of a coil depend upon?
